①Feather Key Jaw Coupling 20mm Diameter 25 Length Spider Jaw Coupling
The 20mm diameter feather key jaw coupling with 25mm length represents a specialized power transmission solution that combines the reliability of traditional jaw coupling design with secure keyed shaft connection. This compact coupling features interlocking jaws paired with a precision-engineered feather key slot, ensuring positive torque transfer while maintaining the coupling's inherent ability to accommodate minor misalignments. The integrated keyway provides enhanced rotational security compared to standard clamp-style connections, making it ideal for applications requiring precise angular positioning or where sudden torque reversals may occur. Despite its secure connection method, the coupling retains the vibration-dampening qualities characteristic of jaw-type designs through its elastomer spider insert, which absorbs shocks and compensates for slight axial, angular, and parallel displacements. The 25mm length offers optimal flexibility in space-constrained installations while providing sufficient material strength for typical industrial loads. Designed for use in precision machinery, servo systems, and equipment requiring both accurate shaft positioning and vibration isolation, this coupling demonstrates how keyed connection security can be effectively combined with the operational benefits of jaw coupling technology. The feather key version maintains all the advantages of standard jaw couplings - including easy installation and maintenance-free operation - while adding the positive drive assurance needed for more demanding motion control applications, offering machine designers a versatile solution that bridges the gap between flexible and rigid coupling requirements.
②Features and applications of jaw coupling
Coupling is a component used to connect a drive shaft and a driven part, for example, a motor shaft and a ball screw for the purpose of transmitting the torque.
The main roles of a coupling include the following:
1.Connecting drive shafts of motors, etc. with driven shafts of ball screws etc. to transmit power.
2·Providing tolerance for errors (misalignment) between the cores of the drive shaft and the driven shaft.
3.Absorbing equipment impacts and vibration.
4·Improving equipment performance.
Also, Coupling introduces mechanical flexibility providing misalignment for the shafts. As a result, this coupling flexibility can prevent uneven wear, vibration, and other mechanical troubles due to misalignment.
